3.2.2 

Input 2 Operation 

Input 2 of the UDC2500/3200 can be used as monitor inputs to the Orion-M.  When Loop 2 Input is selected 
as  the  monitor  input  type  in  the  Orion-M  Configurator,  the  Orion-M  will  display  the  second  input  of  selected 
loop controls as monitor inputs. 
 
The Loop Input 2 monitor point selection allows inputs to be displayed on the Orion-M with a resolution of 0 to 
3 decimal points.  The Orion-M has a display range of -32768 to 32767, -3276.8 to 3276.7, -327.68 to 327.67 
or -32.768 to 32.767 depending upon decimal point selection.  When selecting the decimal point resolution for 
the  monitor  point  input  in  the  Orion-M  Configurator,  make  sure  that  range  of  the  UDC2500/3200  does  not 
exceed the range selected in the Orion-M or the value may not be displayed correctly.   
 
If input 2 of the UDC controller is a temperature value, its temperature units must match that of the selection 
in the Orion-M.   If the selections do not match, the Orion-M may show units of degrees Centigrade while the 
actual value from the UDC control is  in  degrees Fahrenheit.  Be sure that all temperature inputs to all  UDC 
controllers match the temperature units selection on the Degrees C/F screen on the Orion-M. 
 
When using the second input of control loops for monitor points, it is important to note that the controller itself, 
provides  range,  calibration  and  input  bias  settings  for  the  input.    The  ‘Monitor  Input  Offset’  screen  in  the 
Orion-M  runtime  application  allows  an  offset  to  be  applied  to  the  monitor  points  when  input  2  of  the  loop 
controls are used.  However, the input offset of the Orion-M only corrects the value shown on the Orion-M and 
does not offset the reading in the loop control. 
 
If the loop control is visible to the operator, it is recommended that the ‘Monitor Input Offset’ screen be hidden 
(see  Section  3.6  Orion  Functions/Startup  View  in  the  Orion-M  Configuration  Manual)  or  even  password 
protected in the runtime application to prevent an offset from being applied to the monitor point in the Orion-
M.  Rather, use the input bias setting of the loop control so that both the reading on the loop control and the 
Orion-m will match to avoid operator confusion. 
 
 

3.3  Control Output Assignments 

The  Orion-M  uses  a  default  resolution  of  1  decimal  point  to  display  the  percentage  of  output  of  all  UDC 
controllers attached to the system.  Therefore, regardless of the display resolution set on the UDC2500/3200, 
the Orion-M will display a percentage of output of 0.0 – 100.0% for the output. 
 
If the UDC controller is set for bimodal operation (heat/cool), a display value of 50.0% indicates that both heat 
and cool outputs are off.  Values from 50.0 to 100.0% represent the percentage of heat output from off to full 
on and values from 50.0 to 0.0% represent the percentage of cool output from off to full on. 
 
 

3.3.1 

Auto-Tune and Auto/Manual Operation 

The  Orion-M  provides  the  ability  to  switch  each  UDC2500/3200  in  the  system  between  auto  and  manual 
output operation.  This function is accessed from the Orion-M runtime, Single Loop View screen via the ‘AM’ 
control button. 
 
The  Orion-M  cannot  initiate  the  tune  functions  on  the  UDC2500  or  UDC3200  controller.    Pressing  the  ‘AT’ 
button on the Single Loop View screen in the Orion-M runtime will provide the appearance that it will activate 
the  auto-tune  on  the  control,  but  once  initiated,  it  will  immediately  turn  off.    Attempting  to  activate  the  auto-
tune function will not cause any malfunction or system error; however, it should be noted that the function is 
inoperative  when  using  the  UDC2500/3200  control.    Auto-tune  must  be  manually  initiated  at  the  UDC 
controller itself if the function is required.
